Abstract
The invention relates to a timing system disassembly and assembly clamp, comprising a plate body; the plate body is provided with at least two chucks; the head of the chuck is provided with a concave part which is used for clamping the article to be clamped. The invention also discloses a usage method for the timing system disassembly and assembly clamp. The clamp of the invention clamps the fixed bolt of an air intake/exhaust cam shaft timing gear by the chucks, which avoids the change of timing phase when the timing system is replaced, subsequently replaces the parts of the timing system, and has convenient and fast usage.
Description
Technical field
The present invention relates to automobile engine mounting technology field, especially a kind of jig for dismounting timing system and using method thereof.
Background technology
Car engine timing system generally has several kinds of drive such as timing flute profile belt, chain and gear.For the Timing Belt transmission system, because the service life of Timing Belt is limited, so engine wants regular replacing timing flute profile belt to guarantee the timing system reliability service.
For the Timing Belt drive system, its timing mode generally is with special-purpose timing frock bent axle and twin cam shaft to be fixed, and guarantees to adorn timing flute profile belt behind the timing phase.If car load will be changed Timing Belt, engine need be hung out car load, after systematic parts such as the timing cover of front end and valve chamber cover are dismantled, with the timing frock twin cam shaft and bent axle could be changed Timing Belt after fixing, so workload is quite big.
Summary of the invention
Primary and foremost purpose of the present invention is to provide a kind of jig for dismounting timing system that can change twin cam shaft timing system part quickly and easily.
For achieving the above object, a kind of jig for dismounting timing system provided by the invention comprises plate body, and plate body is provided with at least two chucks, and the head of chuck offers and is used for the recess that gripping object is treated in clamping.
Another object of the present invention is to provide a kind of using method of jig for dismounting timing system, this method comprises the step of following order:
(1) forwards crankshaft toothed wheel and import/exhaust camshaft timing gear to the timing position, clamp the set bolt of import/exhaust camshaft timing gear again with the chuck of anchor clamps;
(2) change Timing Belt or stretcher tightening belt;
(3) take off chuck, load onto timing cover.
The present invention clamps the set bolt of import/exhaust camshaft timing gear by chuck, has avoided that timing phase changes when changing the part of timing system, changes the part of timing system subsequently, and is easy to use, quick.
Description of drawings
Fig. 1,2,3 is respectively front view of the present invention, left view and vertical view;
Fig. 4 is the structural representation of timing system.
The specific embodiment
Embodiment one
A kind of jig for dismounting timing system, comprise plate body 30 and at least two chucks 20, chuck 20 is arranged on the two ends or the homonymy of plate body 30, the head of chuck 20 offers and is used for the recess that is non-round shape 21 that gripping object is treated in clamping, in the present embodiment, recess 21 is rectangular, plate body 30 is tabular, offer at least two through holes 31 that can supply bolt to pass on its plate face, the cross section of through hole 31 is a slotted hole, so that regulate the position of chuck 20 on plate body 30, bolt 10 passes chuck 20, plate body 30 is connected with nut 40, plate body 30 and chuck 20 are two parts independent of each other, and the two is connected with nut 40 by bolt 10, as shown in Figure 1.
In conjunction with Fig. 1,2,3, near offering the through hole that can supply bolt 10 to pass on the end of plate body 30, bolt 10 passes chuck 20 successively, plate body 30 is connected with nut 40 on the chuck 20.
Below in conjunction with Fig. 1,2,3,4 the present invention is further illustrated.
In conjunction with Fig. 4, timing system comprises import/exhaust camshaft timing gear 50, idle pulley 60, water pump gear 70, crankshaft toothed wheel 80, regulating wheel 90 and Timing Belt 100, since change the correctness that Timing Belt 100 or stretcher at first will guarantee timing phase, therefore, when changing the parts of timing system, at first to forward crankshaft toothed wheel 80 and import/exhaust camshaft timing gear 50 to the timing position, bent axle be fixed with the bent axle alignment pin; Open the timing gears cover cap then, clamp the set bolt 51 that is used for fixing import/exhaust camshaft timing gear 50 simultaneously with the recess 21 of chuck 20, fastening nut 40, import/exhaust cam shaft gear 50 is fixing, to avoid after removing Timing Belt 100, causing import/exhaust camshaft timing gear 50 and crankshaft toothed wheel 80 to rotate; At last, change Timing Belt 100 or stretcher tightening belt, take off chuck 20, take off the bent axle alignment pin from the bent axle dowel hole again, load onto timing cover.Operate under the consummate situation the maintenance personal, also can omit the bent axle alignment pin, directly crankshaft toothed wheel is gone to the timing position, the set bolt 51 that clamps import/exhaust camshaft timing gear 50 with chuck 20 gets final product again.
Embodiment two
Embodiment two is with the difference of embodiment one: a kind of jig for dismounting timing system, comprise plate body 30 and at least two chucks 20, and chuck 20 is arranged on the two ends or homonymy of plate body 30, and plate body 30 is tabular, and chuck 20 is fixed with one with plate body 30.
In use, the recess 21 of chuck 20 is stuck on the set bolt 51 of import/exhaust camshaft timing gear 50, makes chuck 20 bolt 51 that is fixedly clamped.All the other contents of embodiment two are with reference to embodiment one.
Embodiment three
Embodiment three is with the difference of embodiment one: a kind of jig for dismounting timing system, comprise plate body 30 and at least two chucks 20, plate body 30 is along offering guide groove on its length direction, chuck 20 can slide in guide groove, guide groove is the through hole that the cross section is slotted hole, offer on the chuck 20 and can supply bolted connecting hole, chuck 20 can be by being bolted on the plate body 30.
In use, can be according to the spacing of the set bolt 51 of import/exhaust camshaft timing gear 50, reconcile two positions of chuck 20 on plate body 30, after adjusting finishes, with bolt that chuck 20 is fixing, the recess 21 of chuck 20 is stuck on the set bolt 51 of import/exhaust camshaft timing gear 50, makes the chuck bolt 51 that is fixedly clamped.All the other contents of embodiment three are with reference to embodiment one.
In sum, the present invention clamps the set bolt 51 of import/exhaust camshaft timing gear 50 by chuck 20, the present invention can be under the situation at any phase angle of engine fixing import/exhaust camshaft timing gear 50, to guarantee when changing the parts of timing system such as Timing Belt, avoid import/exhaust camshaft timing gear 50 because the former thereby rotation of valve elastic force or in-cylinder pressure, in addition, the present invention is quick and easy to use, degree of accuracy height.
